Waveform

Article

A waveform is the shape of a signal as it changes with time, position, phase, or another independent variable. It may represent voltage, sound pressure, displacement, light intensity, or another measurable quantity.

Common periodic waveforms include sine, square, triangle, sawtooth, and pulse waves. Each has a distinct shape and harmonic spectrum.

Waveforms are described using amplitude, frequency, period, phase, duty cycle, offset, rise time, and other parameters. Fourier analysis can represent complex waveforms as combinations of sinusoidal components.

Waveform analysis is used in mathematics, electronics, acoustics, communications, control systems, seismology, music, imaging, and computer graphics.
